The source files are whatever licence you received it under.  It's
like asking "if I have book here, is it borrowed, sold, or a gift?
Can I rip out pages?".  The question does not make sense.  Now if the
book carries an inscription "Dear Carthik, I am a great fan of yours
and would like to give this book to you to do whatever you want with
it", then it is a reasonable assumption that you can do whatever you
want with it.  If it later turns out that this book was actually
stolen from somebody, you have to hand it back.  But you'll probably
not be punished even if you tore out pages from that book, as you were
led to expect it is yours.  If the book just ends up at your door
without any clue about its origin and you tear out pages and the next
day your neighbour asks whether his book was delivered to your door,
you could get into trouble.

Even though in the front of the book there is small print allowing
the owner of the book to rip out pages.

Then ask the person that gave it to you.  Nothing else solves this
question.  Software does not magically become GPLed because some
smartass packs a licence file together with it.  It does not come
GPLed if you put GPL headers in it, either.  It becomes GPLed if the
copyright holder gives it to you under the GPL, or if someone that
received it in that manner passes it on.

Copyright headers are a rather clear indication that this has
happened, or that somebody is pretending it did maliciously, so they
put you on a reasonably safe footing.  Having an independent licence
file flowing around somewhere is less reassuring.

Whatever parts the person that gave you to it told you is GPLed by
him or somebody else, and for which he can state so with authority.

It seems like the concept does not enter your head.  The licencing is
something governing the transfer of the software, not the software
itself.

You own a book if you acquire it from somebody who owns it.  Not
because there is some small print in the book that tells you that you
own it.
